I have tried one of those but prefer the air popper. It's basically a vertical hairdryer you put the seeds in and when they pop the air current takes them out.

Much less waste and you don't need oil, so you can spend those calories of flavoring. Just don't overfill it.

Yes, it can be done. There is a lot of useful information on the internet though.

As someone who has tried to program in an environment where you cannot download IDEs without an admin's intervention, access maven central, or just execute code you wrote, holy shit do I not want to live in that world though.
